I haven't given up yet - I just lost my helper for a while (she's a teacher and has been spending more time at school than at home). Once our schedules re-align, I'll do this and report my findings.

Small price to pay for periodic maintenance.
A new battery is definitely on the list of things to do, but I don't want to spend the money on that right now when I haven't proven what is causing this. I would think that with the battery still providing 12+ volts, along with the assistance of the battery charger, that this set up would overcome a weak battery. What is really throwing me is the battery will engage the starter when jumping it to pin 6 of C106 but won't when going through the full starting circuit - that tells me the battery is strong enough to at least trouble shoot with. Also, the "blip" of 12VDC on that pin 6 of C106 and then going to nothing I think is the problem. That (to me) is something in the logic of that starting circuit that isn't holding 12 volts on that pin for a few seconds. And, the RCM has been redone by DJ and given a clean bill of health, but I'll still check the relays to make sure they are doing what they are supposed to do.
Thanks again for all the ideas and comments - much appreciated!!
